1. Before CNC processing, use the calibration to check whether the tool is swinging within the allowable tolerance range. Before processing, use a wind gun to blow the knife head and lock nozzle, or wipe it with a cloth to install the knife. Accuracy and quality have a certain impact.

2. The program list of CNC processing files should be returned, including models, names, program names, processing content, tool size, feed, especially the safety length of the knife clip, the reserved amount of each program and the indicator lights Essence knife. It must be clearly pointed out.

3. The list of procedures should be consistent with the reference angle direction indicated by the mold, and then check the upper 3D diagram, especially the workpiece that has drilled water transport. You must check whether the level of 3D diagrams and workpieces is consistent.

4. Before processing, you must understand the content of the CNC processing program. The program must have 2D or 3D stickers, and it must be marked with six sides of "X long, y wide, Z high". It is convenient for operators to check whether the data is correct after processing. When there is a tolerance, you should indicate the tolerance data.

5. Reasonable use of CNC machining tools should strictly distinguish between steel and the processing of bronze knife. The remaining amount of the light knife should be reasonable, so that the smoothness of the workpiece and the service life of the tools should be possible. better.

6. When clamping, please pay attention to whether the name and model of the CNC processing workpiece are the same as the model list, whether the material size matches, whether the clamp height is high enough, and the number of card ulnar used.

7. CNC processing speed should be strictly controlled by operators. F speed and S's spindle speed should be adjusted reasonably. When F speed is fast, the main axis of S should be accelerated. The speed of the paper must be adjusted in different areas. After processing, there is no problem with the quality of the inspection, and then you can get out of the car and perform perfect processing.
